Example of Multi-Bank System
If you place and configure more I/O modules and I/O banks than
your controller can support, your system may run well for a period
of time. Nothing alerts you to the fact that you have exceeded your
controller’s capacity.
However, by exceeding your controller’s I/O capacity, you put your
system at risk of intermittent faults, the most common being Major
Fault Type 03 (I/O Fault) Code 23.
